若依前后端分离框架技术架构 若依前端模板

目的：为了实现自定义打印模板，采用vue easy print 组件，vue easy print已集成，全部做完再写

 

若依集成的是quill富文本，没有表格功能，打印模板许多是需要用表格的形式组织

wangEdiotr5官网：wangEditor

第一步：安装

yarn add @wangeditor/editor-for-vue
# 或者 npm install @wangeditor/editor-for-vue --save

第二步：下载 wangEdiotr的vue2 demo

第三步：在前端，src，compontes文件夹下，新夹一个wangEidtor/index.vue，封装为一个组件，方便调用

第四步：为便于测试，新建一个页面，名为test，直接复制若依自带公告页面system/noitice,
在ruoyi新建一个菜单，路径指向这个test。
先复制，notice的所有代码，这里
修改使用的组件，引入组件，

直接像原来的Editor一样使用。

wangEdiot组件代码：这是难点

先将，wangEditor VUE2 demo myEdiotr中的代码粘过来，再根据若依原来的Editor组件去修改。

wangEditor 找不到VUE的写法，参考了这篇文章，再次感谢
在editotrconfig中，指定customUpload 要调用的method
           MENU_CONF: {
             // 配置上传图片
             uploadImage: {
               customUpload: this.update
             },

使用自定义上传，原本想用自定义选择图片，上传成功后，需要用insterFn将url写入编辑器，insterFn这个方法不知道在哪找，所以去掉若依使用的el-upload，用wangEditor的选择文件，自己写个上传方法update
加上若依原来editor中的handleBeforeUpload方法，用来检查上传文件

还要引入axios，gettoken,指定header 和 uploadurl ，参考若依原来的Editor
这里返回的内容在res.data中，所以用res.data.code

//自定义上传图片
       update(file, insertFn) {
         if (this.handleBeforeUpload(file)) {
           let formData = new FormData()
           formData.append('file', file)
           axios({
             method: 'post',
             url: this.uploadUrl,
             data: formData,
             headers: this.headers
           }).then(res => {
             console.log(res)
             if (res.data.code == 200) {
               console.log("上传成功")
               let url = process.env.VUE_APP_BASE_API + res.data.fileName
               insertFn(url)
             } else {
               this.$message.error("图片插入失败");
             }
           })
         }
       },

绑定原有的动态style，可以从父组件修改编辑器的高度，和上传文件限制

watch监控传参，否则重复打开时，编辑器内容不更新

 在onChange中将编辑器中的内容返回给父组件

onChange(editor) {
         this.$emit('input', editor.getHtml())}

以下是wangEdiot/index.vue

  <div>
    <div style="border: 1px solid #ccc; margin-top: 10px;">
      <!-- 工具栏 -->
      <Toolbar style="border-bottom: 1px solid #ccc" :editor="editor" :defaultConfig="toolbarConfig" />
      <!-- 编辑器 -->

              this.$modal.msgError("图片插入失败");
            }
          })
        }
      },
    },
    mounted() {
    },
    beforeDestroy() {
      const editor = this.editor
      if (editor == null) return
      editor.destroy() // 组件销毁时，及时销毁 editor ，重要！！！
    },


  }
</script>

<style src="@wangeditor/editor/dist/css/style.css"></style>

替换原来的Editor,全局挂载

使用：像原来的Editor一样用就可以了。v-model 双向绑定

<editor v-model="form.noticeContent" :min-height="192"/>

成功
